Organ transplantation saves thousands of lives every year. Despite growing awareness of transplantation, the issue of obtaining organs for transplantation has been controversial for years. Hundreds of people are waiting in lines all the time for transplantation, for whom it is the only hope for a cure. One extremely important factor contributing to the low number of transplants is the low number of organ donations from deceased donors. Nurses are considered key facilitators of the organ procurement and transplantation process. Their knowledge of and attitudes toward organ donation can influence public opinion, as well as the decisions of their families to donate the organs of the deceased. The purpose of our study was to determine the opinions of surveyed nurses about transplantation and the reasons for negative public attitudes toward organ donation. The survey included 793 nurses employed in surgical wards across Poland with varying levels of job seniority. The survey was conducted between September and October 2022. The research tool was a survey questionnaire, consisting of three parts: socio-demographic data, questions assessing the respondents\' knowledge of behavior about transplantation, and a non-standardized tool to measure respondents\' emotional and motivational attitudes toward transplantation. Participation in the survey was anonymous and voluntary. The statistical analysis for independence of variables used the χ 2 test. On the other hand, coefficients based on the Phi and Cramer\'s V test, as well as Kruskal Wallis non-parametric tests for assessing differences (for more than 2 samples) were used to determine the strength of the relationship. During these analyses, in addition to standard statistical significance, the corresponding \"p\" values were calculated using the Monte Carlo method. According to the nurses surveyed, transplantation is a life-saving procedure. A significant proportion of the nurses (85.6%) believe that there are too few donors in Poland. According to 41.8% of the respondents, this is due to the fear of misdiagnosis of death, for 23.4% it is incompatible with their worldview or religion and 31.8% believe it is due to the belief in the inviolability of the human body after death. The survey showed that, in the nurses\' opinion, the reason for objections to organ transplantation is the deficit in public\'s knowledge of cell, tissue and organ donation from both living and dead donors. Therefore it is extremely important to conduct educational campaigns in this regard.

Water treatment has turned out to be more important in most societies due to the expansion of most economies and to advancement of industrialization. Developing efficient materials and technologies for water treatment is of high interest. Thin film nanocomposite membranes are regarded as the most effective membranes available for salts, hydrocarbon, and environmental pollutants removal. These membranes improve productivity while using less energy than conventional asymmetric membranes. Here, the polyvinylidene fluoride (PVDF) membranes have been successfully modified via dip single-step coating by silica-aminopropyl triethoxysilane/trimesic acid/melamine nanocomposite (Si-APTES-TA-MM). The developed membranes were evaluated for separating the emulsified oil/water mixture, the surface wettability of the membrane materials is therefore essential. During the conditioning step, that is when the freshwater was introduced, the prepared membrane reached a flux of about 27.77 L m-2 h-1. However, when the contaminated water was introduced, the flux reached 18 L m-2 h-1, alongside an applied pressure of 400 kPa. Interestingly, during the first 8 h of the filtration test, the membrane showed 90 % rejection for ions including Mg2+, and SO42- and ≈100 % for organic pollutants including pentane, isooctane, toluene, and hexadecane. Also, the membrane showed 98 % rejection for heavy metals including strontium, lead, and cobalt ions. As per the results, the membrane could be recommended as a promising candidate to be used for a mixture of salt ions, hydrocarbons, and mixtures of heavy metals from wastewater.

The release of GPT-4 has garnered widespread attention across various fields, signaling the impending widespread adoption and application of Large Language Models (LLMs). However, previous research has predominantly focused on the technical principles of ChatGPT and its social impact, overlooking its effects on human-computer interaction and user psychology. This paper explores the multifaceted impacts of ChatGPT on human-computer interaction, psychology, and society through a literature review. The author investigates ChatGPT\'s technical foundation, including its Transformer architecture and RLHF (Reinforcement Learning from Human Feedback) process, enabling it to generate human-like responses. In terms of human-computer interaction, the author studies the significant improvements GPT models bring to conversational interfaces. The analysis extends to psychological impacts, weighing the potential of ChatGPT to mimic human empathy and support learning against the risks of reduced interpersonal connections. In the commercial and social domains, the paper discusses the applications of ChatGPT in customer service and social services, highlighting the improvements in efficiency and challenges such as privacy issues. Finally, the author offers predictions and recommendations for ChatGPT\'s future development directions and its impact on social relationships.
